My dad got like that towards the end, he liked to blame his alzheimer's but the way he phrased it made you think he knew what he was doing. "You know how I'm always forgetting things with my condition." Uh huh. Right, dad. He'd steal lighters and try to set things on fire, my mom would take him to buffets and he'd load up his pockets with cookies. Got them banned from a couple with that stunt.
His position was he'd paid his dues (WWII, Korea) and it didn't cost the companies anything. It was all fun and games until someone decided to press charges. The cops refused to take the report due to his service, but that's the mentality of many of them. "I'm owed". Funny thing was, before his mind started to go, his position was "The world owes you exactly 2 things: jack and shit. You want something, earn it." So maybe it is tied to the decline of mental faculties, or maybe they're just entitled assholes. Until you take the time to know, it's hard to really pass too much judgement.
Unless I'm stuck behind one while driving. Then all bets are off and I wish they'd have had a run in with Dr. Kevorkian
